Alarm Clock Kit with ZIP Halo HD for micro:bit
The Kitronik Alarm Clock Kit with ZIP Halo HD for micro:bit provides a fun introduction to features of Halo HD. This kit features a modified version of Halo HD, all of the parts required to build the clock, and also power accessories. To get you started we have included an easy to follow tutorial book which will guide you through building your clock & checking all the LEDs are working correctly with some test code. Once this is done, we can then move online for some further tutorials within MakeCode.
The Kitronik Alarm Clock Kit with ZIP Halo HD for micro:bit features a modified version of Halo HD. This modified version is only available via this kit. The changes are as follows; power is now provided via a 2.1mm barrel jack connection and there is also a coin cell holder fitted to the rear of the board. When a 1220 coin cell battery is inserted, it will then provide power to the RTC chip when no power is being supplied to Halo HD. This ensures that you only have to set up the time for your project once.
POWERING THE ALARM CLOCK KIT:
The ZIP Halo HD supplied with this kit is powered via a 2.1mm Barrel jack connection. The kit is supplied with a 3xAA Battery holder with a DC Jack and also a USB-B to 2.1mm jack cable. The adapter cable is for use with a separate power supply (not included). A regulated supply is produced on the board which is then fed into the 3V and GND connections to power the connected BBC micro:bit, removing the need to power the BBC micro:bit separately. Halo HD has also been fitted with an ON/OFF switch to maximize battery life. Switch it off when not in use and the onboard coin cell will keep the memory of the RTC chip alive.
